To the .sleeve2r1aspring-cli 26.for holding the razorei-nstmment' 1s attached. It is obvious this"`constructionthat-thesleeve' 21, 26, Will have'atendency to ro from from the upper-arm 22 ofthe sleeve 21 and embracing a stop iii- 28, secured to the arm 9. Toinsert the blade of a razor or a like instrument into thecli', -26when-the'casing. 6 has been pushed over t eworking parts and secured tothe ba'selate '11 bymeans of the nuts 4 and 5, as described above, anopening 29 isprovided in the ycasing 6, through which the blade ispushedA between the jaws of the clip 2 6 and preventedy from. going toofar down by the spur 30 of the'arm 23 of sleeve`21.' To prevent thestropping-band 1.3 from bulging much under the 'pressure of the bladeexerted againstl it and to let the stropping-band pass the'- edge orside of the blade under the most advantageous angleduring the stroppingoperation, rollers 31' are ,provided and mounted with' their'lower endson; adjustable screwbearings.l 32, supported by brackets .33, ,zattachedto the inside of the casing 6, While theirup. ler ends are running onconical'steps i311, Whic 'may be secured tlo the casing 6, as

j, shown here, or may form apart of the rollers andrun'm suitable partofthe cas recesses/formed in the top In opera'lionulilie razor or likeblade to be stropped is introduced through the opening' 29 1n the casingand inserted between the jaws ofthe clip 26. By means of the handle I 8the spindle7 1s then rotated, thus driving the band-13 and carrying withit the sleeve 2l, thereby causing the edge of the blade to press againstthe stropping-.band Withv a substantially constant pressure during theWhole 'time the spindle 7 continues to rotate in one direction, thepressure of the blade against the bandbeing independent of the speed atwhich the handle -is turned and being solely governed by the frictionbetween the cones 19 and 20 and the sleeve 21,A which friction 'can beregulated by adjusting the spring 25, as described above.. After oneside of the blade has been sufliciently stropped and the other side ofthe blade has to be brought into contact With the str'opping-bandA itbecomes only necessary torotate the handle 8 in the opposite direction,and immediately the blade 1s carried out ofcontact with that side of thecontact with the band and is moved to the too y-if desired-fas, forin'stance loopl formed by the band-and put into contact not sufiicientto reach to the stropping-band,

rotation of the sleeve 21 is arrested by the fork 27 en aging thestop-pin 28.

In use t e best results are obtained by rotating the handle through'fouror ve revoluV tions first in one direction and then in the otherdirection, opposite sides ofthe blade being thus alternately. pressedagainst the stropping-band which by reason ofthe arrangement of t egearing. always moves on the operating side from the'backof the bladetoward the edge thereof. Immediately on the reversal of the direction ofmotion of the band the edge of the blade is carried out of opposite sideof the loop formed by the band.

While I have l'shown the preferred iconstruction of the apparatusembodyingy myk invention, it will be understood that I may vary thedetails of construction of the same, 4giving the casing a rectangularform or add any well-known mechanism to admit of reversing the motion ofthe band 13 and of the clip 26-without reversing the motion of thehandle or let the blade to be stropped come into contact with theoutside of the looped stropping-band; but all such chauves would in noWay influ-4 ence the Working el? my apparatus, and therefore fall Withinthe scope of my present invention.

I claim l. An apparatus for stropping razors and like instruments,comprising an endless stropping-bandrevolving when the apparatus isbeing used and capable of being moved in opposite directions, means forholding the blade to be stropped, and means for pressing the bladeagainst the stropping-ban with a` uniform pressure independent of thepull on Vand of the speed of said stropping-band.

2. An apparatus for stropping razors and like instruments coniprisin `anendless revolving stropping-band, ro 1ers for' holding saidstropping-band in a workable position, a spindle rotatably arrangedWithin the loop of said stropping-band, means for simultaneouslyoperating said stroppin -band and said. spindle, a clip for holding t ebla-de to be stropped, and frictionally mounted on said. spindle,and'means for regulatin Vthe friction between said clip and said spinde.

3.
